commit 59ed695d6058fac2eb82fe778b04abe1a55283ba

i945/gma.c: generate fake VBT

This generates a fake VBT for the Intel i945 graphic device.
    i945 supports both the mobile chipset 945gm (calistoga)
    and the desktop chipset 945gc (lakeport),
    which is why a VBT with a different id string
    needs to be created for each target.

The VBT id string is obtained from the vbios blob in the following way:
    "strings vbios.bin | grep VBT".
